Creative Targets Make Aiming Fun & Urinals Cleaner

What unsustainable behaviour needs to change:

In men’s urinals at airports, train stations, stadiums, concert venues, and other busy public areas, a common cleaning challenge is the high rate of soiling due to rushed and distracted users. These environments are frequently used by travelers, sports fans, and concert-goers who may be tired, preoccupied, or hurried due to long queues, which makes maintaining focus on cleanliness more challenging. As a result, operators face the constant issue of splashback and mis-aiming, adding  to both cleaning time and costs.

To address these issues, many facilities attempt to use informational signs–however, these rarely result in lasting improvements. High soiling not only increases cleaning budgets but also uses large quantities of water (often drinking water), which intensifies environmental strain.

The Green Nudge:

A simple yet highly effective nudge involves placing small images or objects within urinals to provide an enticing and fun target for users. This approach not only directs aim but also uses playful imagery to hold attention, reducing splashback and promoting a cleaner environment.

One of the most famous examples is from Amsterdam’s Schiphol Airport, where urinals were fitted with tiny fly images in the early 1990s. This low-cost adjustment led to an impressive 80% reduction in spillage and an 8% decrease in cleaning costs. Richard Thaler and Cass Sunstein highlighted this approach in their influential book “Nudge” as a classic example of „nudging“—a small, non-intrusive prompt that guides behaviour by leveraging natural tendencies, such as aiming for a target.

However, it’s important to note that these figures are based on anecdotal evidence rather than formal studies. Aad Kieboom, who was involved in implementing “the fly at Schiphol,” acknowledged that the 80% reduction estimate was „very empirical,“ and no scientific research was conducted to validate this claim.

Today, creative designs for urinal targets, from dots to soccer goals, show how these nudges can make public and private facilities cleaner and more sustainable, thus reducing cleaning frequency and water use. This small change delivers large benefits in terms of resource conservation and environmental impact.
